Capillarity, the process of the rise or fall of the floor or level of the fluid in the capillary, is called capillary or capillary. The duct is a tube with a very microscopic transverse area that when immersed in a fluid, the surface of the capillary rises slightly. Goes or falls below, the rise or fall of the floor in the capillary depends on the nature of the fluid in which it is being immersed. When the capillary is immersed in a fluid that soaks the solid, the floor or level of the fluid in the capillary rises. When the capillary is immersed in a fluid that does not soak the solid, when immersed in such a fluid, the bottom of the fluid in the hair tube falls down. Let's test yourself with Capillarity and Capillary Tube Trivia Quiz.
